Just updated app w/ Xcode 7, getting a crash on initialization in UIApplicationMain, seemingly due to fonts.

(I noticed that Xcode 7 put a customFonts entry in my main .xib file .. maybe related?)

+    <customFonts key="customFonts">
+        <mutableArray key="Helvetica.ttc">
+            <string>Helvetica</string>
+            <string>Helvetica</string>
+            <string>Helvetica</string>
+            <string>Helvetica-Bold</string>
+            <string>Helvetica-Bold</string>
+            <string>Helvetica-Bold</string>
+            <string>Helvetica-Bold</string>
+            <string>Helvetica</string>
+        </mutableArray>
+    </customFonts>

This is the debugger hitting a breakpoint, not a crash. You have presumably set a breakpoint on all exceptions, including for C++ (as opposed to just Objective-C). The thing is, unlike Objective-C, exceptions are sometimes used in "normal" situations by C++ code. They don't necessarily indicate an unrecoverable error or impending crash.


In general, unless you're debugging C++ code and specifically interested in the exceptions thrown by it, you should set your breakpoint to just stop on Objective-C exceptions. Ignore the C++ exceptions. They will most likely be caught and handled by the C++ code and not actually cause any problem.

I'm also seeing this. I just upgraded my device from iOS 8 to 9, and the issue suddenly started to occur. Did you by any chance resolve it?


No breaking on C++ exceptions didn't fix it. Also, I removed all custom fonts from my project, and that also did not eliminate the issue.


Funny enough, disabling "debug app" in my scheme prevents the crash from occurring. But that's obviously not an option as I won't be able to debug the app at all as I'm developing it.
